Research ArticleOpen accessIn the abstractSELECTIVE ISOLATION OF A GRAM NEGATIVE CARBAMATE PESTICIDE DEGRADING BACTERIUM FROM BRINJAL CULTIVATED SOILDilara Islam Sharif, Mithun MollickA bacterial species having the ability to grow in the presence of carbosulfan pesticide “Marshall” was isolated from Solanum melongena (brinjal) cultivated soil in Khulna region, Bangladeh, having a history of pesticide usage. The strain was morphologically and biochemically identified to belong to the genera Pseudomonas. A comparative study of growth of this strain with other isolated bacteria showed its … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 4 · 24 Sep 2013 · 7,455 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntibiotic Resistance and Chromium Reduction Pattern Among ActinomycetesPreeti Jain, Alina Amatullah, Samiul Alam Rajib, Hasan Mahmud RezaActinomycetes, one of the most important groups of microbes, exhibit many interesting activities such as degradation and transformation of organic and metal substrates together with production of antibiotics. With these bioactivities, actinomycetes would play an important role in the webs of the marine environment. The present study was designed to evaluate the antibiotic resistance pattern, antibiotic producing potential and chromium … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 2 · 22 Jun 2012 · 8,908 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Dose-Response of Zinc and Manganese on Siderophores ProductionMehri Ines, Khessairi Amel, Turki Yousra et al.Problem statement: This study was conducted to find and determine whether the siderophores of the four environmental Pseudomonas spp. isolates possess a sequestering activity towards essential transition metals (Zn and Mn) other than iron. Approach: Four fluorescent Pseudomonads isolated from various environments, were characterized analytically (Isoelectric focusing), biologically (pyoverdine-mediated uptake) and genetically (16S rDNA sequencing). By means of spectrophotometric measurements, … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 10 Mar 2012 · 7,772 accessesView PDFCite
Research ArticleOpen accessIn the abstractLocalization of the Dissimilatory Arsenate Reductase in Sulfurospirillum Barnesii Strain SeS-3Eman AfkarProblem statement: Sulfurospirillim barnesii strain SeS-3 is one of the recently known bacterial isolates that can obtain energy to support growth by respiring the toxic oxyanions of arsenic and selenium under anaerobic conditions. Approach: The ultimate goal of this investigation is to localize the active sites for the reduction of arsenate arsenite as well as selenate selenite in S. barnesii … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 1 · 5 Mar 2012 · 7,910 accessesView PDFCite
Research ArticleOpen accessIn the abstractDecolorization of Mordant Orange-1 by Marinobacter algicola MO-17R. S. Shertate, Prakash ThoratProblem statement: The textile industries use different types of dyes in their processing units which are liberated in natural marine water bodies. This release of dyes in turn affect the marine flora and fauna very adversely. Approach: The release of textile dyes into the environment is a matter of concern due to the toxicity, mutagenicity, carcinogenicity and xenobiotic nature. Hence, … …OnLine Journal of Biological Sciences, Vol. 12, Issue 1 · 25 Feb 2012 · 7,517 accessesView PDFCite
Research ArticleOpen accessIn the abstractFactors Affecting the Geometry of Silver Nanoparticles Synthesis in Chrysosporium Tropicum and Fusarium OxysporumNamita Soni, Soam PrakashProblem statement: Biosynthesis of nanoparticles using fungal cells is a novel approach to develop biotechnological possess such as bioleaching and bioremediation. In the present study, an effort was made to investigate the effect of physio-chemical parameters on the silver nanoparticle formation with the fungus Chrysosporium tropicum Carmichael and Fusarium oxysporum Schltdl. Approach: The possibilities to manipulating the geometry of silver … …Current Research in Nanotechnology, Vol. 2, Issue 1 · 20 Jan 2012 · 19,459 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiosurfactan Production by Bacillus sp. Isolated from Petroleum Contaminated Soils of Sirri IslandM. Ghayyomi Jazeh, F. Forghani, Deog-Hwan OhProblem statement: Biosurfactants are active surface components produced by some bacteria and fungi. These molecules reduce surface and interfacial tension in aqueous solutions and hydrocarbon mixtures. The most important application of biosurfactants is in oil industry to enhance oil quality and facilitate oil extraction. The aim of this study was to isolate biosurfactant producing bacteria and optimize the conditions like … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 13 Jan 2012 · 8,557 accessesView PDFCite
Research ArticleOpen accessIn the abstractMicrobial Consortia from Taptapani Hot Water Springs for Mining Effluent TreatmentPoonam Nasipuri, Gauri G. Pandit, Ashoke Ranjan Thakur, Shaon Ray ChaudhuriProblem statement: Soluble sulfate load in effluent is a crucial problem from mining industries. The study involved isolation of efficient Sulfate Reducing Bacterial (SRB) consortium from hot water spring for bioremediatrion of sulfate contaminated waste water. Approach: The enriched bacterial consortium was isolated in medium DSMZ 16695. The sulfate reduction efficiency was measured by turbidometric method. The Km and Rmax … …Current Research in Microbiology, Vol. 1, Issue 2 · 31 May 2011 · 8,463 accessesView PDFCite
Research ArticleOpen accessIn the abstractHydrocarbon Biodegrading Potentials of a Proteus vulgaris Strain Isolated from Fish SamplesPatience O. Olajide, L. B. OgbeifunA Proteus vulgaris bacterium SR-1 was isolated from a freshly killed fish sample collected close to the point of crude oil spill in the Niger Delta region, Nigeria. Problem statement: The application of native bacterial species in bioremediation processes has long been desired, because they would be cost effective and efficient in terms of acclimation time.
